It is possible for applications to configure Berkeley DB at
|
||
run-time to redirect Berkeley DB library and system calls to
|
||
alternate interfaces. For example, an application might want
|
||
Berkeley DB to call debugging memory allocation routines
|
||
rather than the standard C library interfaces. The following
|
||
interfaces support this functionality:

These interfaces are available only on POSIX platforms and
|
||
from the Berkeley DB C language API.
|
||
</p>
|
||
<p>
|
||
A not-uncommon problem for applications is the new API in
|
||
Solaris 2.6 for manipulating large files. Because this API was
|
||
not part of Solaris 2.5, it is difficult to create a single
|
||
binary that takes advantage of the large file functionality in
|
||
Solaris 2.6, but still runs on Solaris 2.5. <a class="ulink" href="solaris.txt" target="_top">Example code</a> that supports this
|
||
is included in the Berkeley DB distribution, however, the
|
||
example code was written using previous versions of the
|
||
Berkeley DB APIs, and is only useful as an example.
